From the page: "Spirit [to Phoenix]: I have survived 5 years on Mars, power malfunctions, and a broken wheel. You, Sir, are FAIL.
Opportunity: Agreed."
it sounds like they didn't have a way to verify that the lower stage had finished its burn, before attempting separation. this is a good lesson in vehicle design :P
From the page: "To the surprise of mission experts, satellite Explorer 1 changed rotation axis after launch.

a fine example of how investment into the space program has produced new technologies to improve consumer goods. thanks to ar0cketman
this is excellent. in science, the biggest head-scratchers can lead to the best new models. with luck, maybe this will help us connect gravity and quantum mechanics (just hoping...)
